Rice flour mixed with oat fibre and plant compounds in mice

What it found

Adding a specific oat fibre and plant compound mix to rice flour slowed digestion and blood sugar rises in mice.

The higher-weight version of the mix worked best.

What they found

Animal and lab studies

Lab antioxidant tests

In lab tests, the heavier mix showed stronger ability to neutralise free radicals than the lighter one. It also blocked starch-digesting enzymes more effectively.

Stomach emptying in mice

Mice eating rice flour with the heavier mix had the slowest stomach emptying. Their gut movement was also slower than in the other groups.

Blood sugar in mice

The heavier mix led to the smallest rise in blood sugar after eating rice flour. Insulin levels were also lower in these mice.

Digestive hormones in mice

Mice given the heavier mix had lower levels of hunger-related hormones like ghrelin and motilin. Activity of digestive enzymes was also reduced compared to the control group.

What the authors conclude

  • They suggest the heavier mix of oat fibre and sea buckthorn compounds slows stomach emptying and lowers blood sugar responses when added to rice flour.
  • Their findings offer data for making foods that digest slowly for people who need them.

How it was done

Mixing oat beta-glucan with plant compounds is known to slow starch digestion and blood sugar responses. Scientists wanted to understand how this affects stomach emptying and the reasons behind it.

Researchers tested two versions of an oat fibre and sea buckthorn compound mix, one heavier and one lighter. They ran lab tests on both, then fed rice flour with the heavier mix to mice. They compared those mice to others eating plain rice flour or rice flour with the lighter mix.

What it can’t tell you

  • We summarised it from the abstract only.
  • These results come from mice, so they cannot show what happens in people eating rice flour with these ingredients.
  • The study looked at a single meal situation, so scientists do not yet know the effects of eating this regularly over time.
